Maple Cross is a village in Hertfordshire, England, with a large proportion of the housing being either council owned or previously council owned.

The bus route R21 runs from Mount Vernon Hospital via Harefield and Rickmansworth. It normally terminates at Maple Cross, but extends its journey to Uxbridge twice per day via Denham.
Sewage treatment plant
Maple Cross is the location of the Thames Water Maple Lodge Sewage Treatment Works. The plant, with its sister site at Blackbirds Farm in Aldenham serve the whole of West Hertfordshire; an area with a population of 557,000 people.
The sewage plant's claim to fame is its use as a storage facility for perfluorooctane sulfonate (PFOS) used to extinguish the fire at the Buncefield Oil Terminal. Sludge from the plant was also burnt to generate "green" electricity for the Millennium Dome.
The plant was used in 1952 to test diffused aeration technology and a diffused-air activated sludge purification system has been in continuous use since. The cleaned effluent from this process is discharged into the nearby Grand Union Canal.
Sludge settled from the incoming sewage is treated by retention in enclosed heated anaerobic digestion tanks, a by-product of this process being methane gas which is used for on-site electrical power generation. The main product, digested sludge, is "caked" in industrial centrifuges before disposal to land as fertiliser.
There is a 40 acre nature reserve on Thames Water owned land formerly used for gravel extraction, adjacent to the sewage treatment plant. It includes lakes and wetlands that provide a habitat for wildfowl and nine Bird hides. The reserve is leased to the Maple Lodge Conservation Society that was founded in 1983. Access is normally restricted to members of the society with an open weekend in May.
